The crowd is in a frenzy now, and will remain so as six more buses pull up, most of them nearly empty, during the next 20 minutes. The first small group of kids enter the building without incident, as the photographers dash after them, and a second bus comes almost immediately. Moments after the second group of black kids gets safely into the building, the first violence erupts.

Three pickets from the Progressive Workers Party are standing at the curb near the fringe of the crowd, holding signs urging them to "fight racism, not busing" One of the pickets is black; suddenly, as the crowd roars its approval, he disappears in a sea of moving bodies. Police move in momentarily to drag him to safety across the street.

The crowd grows more enthusiastic. They break into the school song ("For Boston, for Boston, the high school on the hill") and when they tire of that, they switch to chants borrowed from last year's football season ("Here we go, Southie, here we go").

It is getting ugly now and the police know it. At 8:07 a line of police reinforcements moves down G Street and fans out facing the crowd.

Two minutes later the first object-- a rock -- is thrown as another bus moves in. Seconds later a bottle comes flying out of the crowd and finally, when the next bus arrives after a delay of several minutes and is met with a barrage of chunks of wood, the police move.

After reportedly issuing an order to disperse (this reporter, in the midst of the crowd, heard no such order), the cops bunch up near the front of the school and push outward, driving the crowd on the sidewalk down the G Street hill. For a few seconds it is brutal: some kids resist, the cops get tough, and there is pushing and shoving in both directions.

Finally all movement is in one direction — down the hill — quickly.

The crowd seems momentarily stunned, as if they had never expected that kind of sweeping police action.

"Can you imagine," says one woman who asked not to be identified, "can you imagine them chasing the kids down the hill like that, even grabbing hold of the girls. Who are they working for, anyway?"

But after a while, the kids all drift back up the hill, in twos and in threes. Their return is a signal that it is not over, that they are ready for more action if given half a chance.

From that point until shortly before the school's 2 o'clock closing, the prevailing mood was that of a summer carnival, complete with guest appearances by Chester Broderick, head of the policeman's union, by Southie representative Ray Flynn, and by the city's best-known busing opponent, City Councillor Louise Day Hicks ("The people have shown great restraint," said Mrs. Hicks).

But the surface mood was deceptive, and violence erupted several times. A black teacher who appeared outside the school became the target of tomatoes and bottles and a TV cameraman was roughed up, apparently when he bumped into someone in the crowd.

Fourth-estate follies, 2009 edition Between the rise of the Web, the ADD-addling of America, the fragmentation of any national political consensus, and the devastated economy, working in the press can feel a bit like manning the Titanic — and this year, the entire industry seemed to teeter on the edge of oblivion.

Racism in real estate After more than a decade in the business, the real-estate agent knew that many landlords had very narrow ideas about whom they did and didn't want living in their apartments and houses. Most of them were fairly subtle about it. "I want the right people," they might say, being careful to couch their instructions in innocuous-sounding terms.

Murdoch mishegoss Never mind that Rupert Murdoch is shelling out better than $2 billion to buy Metromedia’s seven TV stations. Never mind that he’s then turning around and reselling Boston’s WCVB-TV, Channel 5 to the Hearst Corporation for an astounding $450 million.

This must be the place It is a place so confident, so much an institution, as to presume to call itself by its last name. When someone says they’re going to the Square, nobody expects them to turn up at the Statler Building in Park Square or under the CITGO sign in Kenmore Square or in Elmer N. Buswell Square.

Lynch’s left flank US Representative Stephen Lynch has held Massachusetts’s ninth congressional district since 2001 — a fact that has irritated the state’s liberals ever since.

What's missing? After an intense investigation into the backgrounds of Republican Governor Paul LePage's nominees for top administration posts, I've discovered an astonishing lack of diversity.

Anti-diversity is bad for business As he has done with environmental leaders, Governor Paul LePage needs a forum to hear from Maine immigrant and civil-rights leaders. This is made all the more urgent when one considers his "kiss my butt" sound-bite refusal to meet with the NAACP because they are a "special interest."
